Title: Ultrasonic flaw detecting method
Inventor: YAMADA RYUZO
IPC: G01N29/04
Filed: 1998-04-09
Abstract: PROBLEM TO BE SOLVED: To provide an ultrasonic flaw detecting method capable of simply inspecting the state of bonding at a plurality of bonded sections of an object to be inspected through the use of one ultrasonic flaw detector and a plurality of probes. SOLUTION: A plurality of probes 20-1 and 20-2 capable of transmitting and receiving ultrasonic waves are arranged at locations corresponding to bonded parts P1 and P2 of an object to be measured W so that the distances of flaw detection may be different. In addition, an ultrasonic flaw detector 10 is directly connected to the probes 20-1 and 20-2. As a result, ultrasonic waves are simultaneously outputted from the probes 20-1 and 20-2, are reflected at the bonded parts P1 and P2 of the work W, and are received by the probes 20-1 and 20-2. As the distances of flaw detection by each of the probes 20-1 and 20-2 are different, the peak of a detection signal corresponding to each reflected wave obtained by amplifying and detecting a reception signal on the side of the ultrasonic flaw detector 10 appears at different timing.  Therefore, it becomes possible to inspect the state of bonding of each of the bonded parts P1 and P2 with accuracy.

Title: Magnetic polishing method for drum face and endface of work
Inventor: HATANO SHIGETO
IPC: B24B31/112
Filed: 1985-05-10
Abstract: PURPOSE:To polish the entire drum face and end face of work uniformly by constructing such that one magnetic pole will have a magnetic pole face facing through gaps against the drum face and the end face of work while the other magnetic pole will have a magnetic pole face extending from the drum face through a gap. CONSTITUTION:One magnetic pole 3 has a magnetic pole face 3a arranged through a gap 4 against the drum face at one side of the drum face 1a of work 1 and a magnetic pole face 3b arranged through a gap 5 in the direction of the end face 1b of work. The other magnetic pole 6 has a magnetic pole face 6a facing through a gap 7 against the drum face while extending outward from the drum face. Consequently, the magnetic flux will concentrate firmly against the drum face and the end face of work in the gaps 4, 5, 7 while the magnetic abrasive grains will entirely cover the drum face and the end face of work not to be dispersed outward upon rotation of work. Since magnetic abrasive grains will adhere and move repeatedly against the surface of work thus to form a new edge against the surface of work, the drum face and the end face of short work can be polished uniformly.

Title: Hot water supplier with hot water storage
Inventor: KANEKO HIDEKI
IPC: F24S90/00
Filed: 1981-06-23
Abstract: PURPOSE:To perform two-stage shift in the volume of hot water kept in a storage, as well as to be able to obtain high temperature water in a short time, by composing a hot water supplier in such a manner that the hot water in a container, in which an electric heater and a solar heat exchanger are built in, can be supplied from either the upper part or the lower part of a can body, by the intermediary of a hot water supplying pipe and a change-over valve. CONSTITUTION:The water fed from a water supplying pipe 10 is heated in a heat exchanger 6 and is fed out of a container 9 into a can body 1 by a natural convection flow, passing through hot water supplying pipes 13 and 11. In this case, high temperature water can be obtained in a short time, if high temperature water is passed through a pipe 11, by operating a change-over valve 14. On the other hand, the whole water in a can body 1 can be heated nearly uniformly, if the change-over valve 14 is changed and high temperature water is led into a can body 1 from a pipe 12. The hot water corresponding to the half volume of the capacity of can body can be reserved, by providing a pipe 11 to the middle part of the can body 1, so that heat radiating loss can be decreased.

Title: Relative speed detecting device and collision preventing device
Inventor: SUZUKI SACHIHIRO
IPC: B60W30/00
Filed: 1990-04-13
Abstract: PURPOSE:To inform a driver of dynamic information by detecting the relative speed between its own vehicle and a precedent vehicle or following vehicle from a road image. CONSTITUTION:The image of the road in front of or behind of its own vehicle is inputted by a video camera 11 and an edge process is carried out for the input image data to detect a lane display line where its own vehicle travels. A travel lane detecting means 13 judges the travel lane of its own vehicle from the detected lane display line and a vehicle detecting means 14 detects the presence of the vehicle from the horizontal edge component of the image in the travel lane. Further, the vehicle distance is found from the position where the detected vehicle and stored in a vehicle distance storage means 16. Thus, the difference between the vehicle distance detected by the vehicle distance detecting means 15 and the vehicle distance detected in a last image plane stored in the storage means 16 is used to find the relative speed of this vehicle to the precedent or following vehicle. Consequently, the driver is informed of the dynamic information automatically.

Title: Purifying apparatus
Inventor: TSUEMOTO TOSHIO
IPC: C02F3/12
Filed: 1978-08-11
Abstract: PURPOSE: To obtain a purifying apparatus capable of always performing stable purification by connecting a plurality of separated chambers with openings in order; setting an aeration pipe in each of the chambers; and successively increasing the vol. of air fed from the pipe per unit vol. of sewage to prevent short circuit of sewage.  
     CONSTITUTION: Sewage from introduction pipe 7 flows round in separated chamber 2 and is fed to aeration chamber 3 through chambers 2a, 2b, 2c in order while being aerated and gradually sedimentation-separating solid matter. Chambers 2a, 2b, 2c become smaller in this order, and the vol. of air blown is almost constant, so sedimentation of the largest amt. of solid matter occurs in chamber 2a. The vol. of air per unit vol. of sewage is successively increased, and aeration of sewage proceeds to avoid such a situation that aerobic bacteria in chamber 3 are destroyed by sudden inflow of BON high concn. sewage, thereby temporarily lowering the purification power (short circuit of sewage).
